The Kolkata class (Project 15A) are a class of stealth guided missile destroyers constructed for the Indian Navy. The class comprises three ships – Kolkata, Kochi and Chennai, all of which are being built by Mazagon Dock Limited (MDL) in India, and are the largest destroyers to be operated by the Indian navy.

The destroyers are a follow-on of the Project 15 Delhi-class destroyers, but are considerably more capable due to major improvements in the design, the addition of substantial land-attack capabilities, and the fitting-out of modern sensors and weapons systems.

Construction:

Construction of three Kolkata-class ships was sanctioned by the Government of India in May 2000, and steel for the lead ship was cut in March 2003. Construction began in September 2003 at Mazagon Docks, Mumbai, with an initial expectation that the first of the class would be handed over to the navy by 2010. However, since then the Kolkata class has suffered consecutive delays, slow construction procedures and technical problems which saw the first ship of the class enter service during mid 2014. The delays in the construction programme have been attributed to persistent design changes made by the Indian Navy to incorporate new weapons systems and sensors, failure by a Ukrainian shipyard to deliver the ship’s propellers and shafts and the contract later being awarded to a Russian firm, and finally the delay in the delivery of the Barak 8 anti-air missiles, which are still in the final stages of completion with Israel Aerospace Industries and the Defence Research and Development Organisation.

The Kolkata class are the largest destroyers ever to be constructed at Mazagon Docks, and as of 2013, all three ships of the class have been launched and are being fitted out. Technical problems were found during the sea trials of the lead ship Kolkata, which delayed the project by six months to early 2014

The Kolkata class share similar dimensions to the previous Delhi class, however they have 2,363 modifications which include major upgrades in weaponry, sensors and helicopter systems. These are the first stealth destroyers being built by India and marked a significant development in India’s shipbuilding technology. The ships would incorporate modern weapons and sensors, and will have an advanced information warfare suite, an auxiliary control system with a sophisticated power distribution architecture, and modular crew quarters.

Ships of the class

INS Kolkata
INS Kochi
INS Chennai

INS Chennai, a P-15A Guided Missile Destroyer, was commissioned into the Indian Navy by the Hon’ble Raksha Mantri Shri Manohar Parrikar at an impressive ceremony held at the Naval Dockyard, Mumbai on 21 Nov 16. The event marks the formal induction into the Navy of the third and the last of the three ‘Kolkata’ class destroyers, indigenously designed by the Indian Navy’s in-house organisation, Directorate of Naval Design and constructed by Mazagon Dock Limited, Mumbai. On his arrival, the Hon’ble Raksha Mantri was received by Admiral Sunil Lanba, PVSM, AVSM, ADC, the Chief of the Naval Staff and was presented a Guard of Honour by the ship’s crew. The ceremony was witnessed by a large gathering which included several dignitaries and senior officials from the government and all three services.
Hon’ble Raksha Mantri Sh Manohar Parrikar, whilst addressing the gathering, termed the commissioning of INS Chennai, last of the Project P-15A class Destroyers, as a historic day for the Indian Navy as it adds another milestone in our relentless journey towards achieving self reliance in battle readiness. The ship represents a significant ‘coming of age’ of our warship building capability and defence preparedness, said the Defence minister. He further stated that the Indian Navy, in addition to providing overall maritime security to our country, also plays a crucial role as the ‘net security provider’ in our adjoining seas. In this regard, Shri Manohar Parrikar also stressed that the Navy’s growth and development must keep pace with the nation’s growth and maritime security needs.

Lauding the role played by the naval designers (DGND) and the ship builders i.e. M/s MDL Mumbai, the Raksha Mantri said “with the induction of INS Chennai, a new benchmark has been achieved for our warship design and construction endeavours, with the sophistication of systems and equipment, and utilisation of advanced ship building techniques”.

During his address, Admiral Sunil Lanba, the Navy Chief said that commissioning of INS Chennai marks another milestone in the Navy’s quest for self-reliance as it signifies completion of the challenging Project P-15A and heralds a new era of advanced warships built indigenously by Indian shipyards. The Admiral also stated that indigenisation of platforms, weapons, sensors and equipment with participation of public as well as private sectors, will continue to remain a focus area of the Indian Navy, in line with the ‘Make in India’ policy enunciated by the Prime Minister. He emphasized that the ‘Roadmap for the Navy’s expansion and growth would continue to remain firmly anchored on Self-reliance and Indigenisation’.

The Commanding Officer, Captain CR Praveen Nair, read out the Commissioning Warrant, which was followed by the hoisting of ‘Colours’ (ceremony of hoisting the National Flag and Naval Ensign) which marked the commencement of the ship’s service as a warship of the Navy. The Commissioning event was characterised by closely coordinated sequence of drills and events leading to formal unveiling of the ship’s name plaque by the Chief Guest. On completion of the Commissioning Ceremony, the Hon’ble Raksha Mantri also unveiled a special cover to commemorate the Commissioning of INS Chennai and completion of the prestigious Project 15A class of stealth destroyers.

Following her formal induction, INS Chennai will be placed under the operational and administrative control of the Flag Officer Commanding-in-Chief, Western Naval Command. In due course, the ship will be assigned to the Western Fleet and would be base-ported at Mumbai.

The ship measures 163m in length, 17.4m in breadth with a displacement of 7500 tonnes and can rightfully be regarded as one of the most potent warships to have been constructed in India. The ship is propelled by four powerful Gas Turbines, in a Combined Gas and Gas (COGAG) configuration, capable of achieving speeds in excess of 30 knots. The ship has enhanced stealth features resulting in a reduced Radar Cross Section (RCS) achieved through efficient shaping of hull, full beam superstructure design, plated masts and use of radar transparent materials on exposed decks.

INS Chennai is packed with contemporary and sophisticated ‘state of the art’ weapons and sensors such as Surface to Surface Missile(BrahMos) and Surface to Air Missiles(Barak 8). The ship is fitted with a modern Surveillance Radar which provides target data to the gunnery weapon systems of the ship. The ship’s Anti Submarine Warfare capabilities are provided by the indigenously developed Rocket Launchers and Torpedo Launchers. The ship is equipped to fight under Nuclear, Biological and Chemical (NBC) warfare conditions.

A unique feature of this ship is the high level of indigenisation incorporated in the production, accentuating our national objective of ‘Make in India’. Some of the major indigenised equipment / system onboard INS Chennai include Combat Management System, Rocket Launcher, Torpedo Tube Launcher, Automated Power Management System, Foldable Hangar Doors, Helo Traversing system, Auxiliary Control System and the Bow mounted SONAR.

Named after the iconic port city of Chennai, the ship has a complement of about 45 officers and 395 personnel. Enhancement of crew comfort has been a significant feature of INS Chennai, which has been ensured through ergonomically designed accommodation based on ‘modular’ concepts. The ship will be under the command of Captain CR Praveen Nair, a Communication & Electronic Warfare specialist.

With the changing power dynamics in the Indian Ocean Region, INS Chennai will augment the Indian Navy’s mobility, reach and flexibility whilst proudly flying the Indian flag.
